Abstract
Abstract Apparatus for taking an X-ray picture of the head of a human being which comprises an X-ray source, an X-ray film holder and a head setting device disposed between the source and the holder. The setting device includes an axially aligned pair of ear rods adapted to be inserted into the holes of the opposite ears and means for moving the ear rods relative to the path of the X-ray beam from the source without changing the relative positions of the ear rods.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
332 words
A head-position adjusting apparatus suitable for use in combination with an X-ray photographic apparatus, wherein an Xray beam is transmitted along a substantially horizontal X-ray axis towards an X-ray film intersecting said X-ray axis, to position the head of a person such that it intersects said X-ray axis, X-ray photographic apparatus, said head-position adjusting apparatus comprising: a support arm adapted to be positioned above said X-ray axis; a pair of spaced support members mounted on said support arm so as to extend outwardly from said support arm in the general direction of said X-ray axis, and adapted to be moved toward and away from one another along said support arm; a pair of ear rods, one of said ear rods being affixed to one of said pair of spaced support members and projecting toward the other of said pair of spaced support members, the other of said ear rods being affixed to the other of said pair of spaced support members and projecting toward said one of said pair of spaced support members, said pair of ear rods defining a straight line, and being movable into and out of the ears of the head of a person when said head is suitably positioned between said pair of spaced support members; ear rod positioning means connected to said pair of spaced support members for simultaneously moving said pair of spaced support members so as to position said pair of ear rods in the ears of the head of a person when said head is suitably positioned between said pair of spaced support members; and head positioning means connected to said support arm for selectively positioning said straight line connecting said pair of ear rods: (a) longitudinally with respect to said X-ray axis; (b) transversely with respect to said X-ray axis in both vertical and horizontal planes; (c) arcuately with respect to said X-ray axis in a generally vertical plane; and (d) arcuately with respect to said X-ray axis in a generally horizontal plane.
Claim 2
Dependent Claim
332 words
A head-position adjusting apparatus suitable for use in combination with an X-ray photographic apparatus, wherein an Xray beam is transmitted along a substantially horizontal X-ray axis towards an X-ray film intersecting said X-ray axis, to position the head of a person such that it intersects said X-ray axis, X-ray photographic apparatus, said head-position adjusting apparatus comprising: a support arm adapted to be positioned above said X-ray axis; a pair of spaced support members mounted on said support arm so as to extend outwardly from said support arm in the general direction of said X-ray axis, and adapted to be moved toward and away from one another along said support arm; a pair of ear rods, one of said ear rods being affixed to one of said pair of spaced support members and projecting toward the other of said pair of spaced support members, the other of said ear rods being affixed to the other of said pair of spaced support members and projecting toward said one of said pair of spaced support members, said pair of ear rods defining a straight line, and being movable into and out of the ears of the head of a person when said head is suitably positioned between said pair of spaced support members; ear rod positioning means connected to said pair of spaced support members for simultaneously moving said pair of spaced support members so as to position said pair of ear rods in the ears of the head of a person when said head is suitably positioned between said pair of spaced support members; and head positioning means connected to said support arm for selectively positioning said straight line connecting said pair of ear rods: (a) longitudinally with respect to said X-ray axis; (b) transversely with respect to said X-ray axis in both vertical and horizontal planes; (c) arcuately with respect to said X-ray axis in a generally vertical plane; and (d) arcuately with respect to said X-ray axis in a generally horizontal plane.
Claim 3
Dependent Claim
173 words
A head-position adjusting apparatus as claimed in claim 1 wherein said head-positioning means comprises: a first arm, said support arm being rotatably mounted on said first arm such that said straight line connecting said pair of ear rods is selectively positioned adjustable arcuately with respect to said X-ray axis in a generally horizontal plane; a second arm, said first arm being mounted on one end of said second arm such that said straight line connecting said pair of ear rods is selectively positioned adjustable transversely with respect to said X-ray axis in a horizontal plane; and, a carriage mechanism, said second arm being rotatably mounted on said carriage mechanism such that said straight line connecting said pair of ear rods is selectively positioned adjustable arcuately with respect to said X-ray axis in a generally vertical plane, said carriage mechanism being suitable for selectively position adjusting said straight line connecting said pair of ear rods longitudinally with respect to said X-ray axis and transversely with respect to said X-ray axis in a vertical plane.
Claim 4
Dependent Claim
83 words
A head-position adjusting apparatus as claimed in claim 2, wherein said carriage mechanism comprises a first carriage element, a second carriage element and a support block, said first carriage element being mounted on said support block so as to be vertically movable with respect to said support block and said second carriage element mounted on said first carriage element so as to be horizontally movable with respect to said first carriage element, said second arm being rotatably mounted on said second carriage element.
Claim 5
Dependent Claim
175 words
A head-position adjusting apparatus as claimed in claim 3, including: a first indicating means associated with said support arm and said first arm for providing a visual indication of the rotational position of said support arm with respect to said first arm; a second indicating means associated with said First arm and said second arm for providing a visual indication of the transverse position of said first arm with respect to said second arm; a third indicating means associated with said second arm and said second carriage element for providing a visual indication of the rotational position of said second arm with respect to said second carriage element; a fourth indicating means associated with said first and second carriage elements for providing a visual indication of the transverse position of said second carriage element with respect to said first carriage element; and, a fifth indicating means associated with said support block and said first carriage element for providing a visual indication of the position of said first carriage element with respect to said support block.
Claim 6
Dependent Claim
106 words
A head-position adjusting apparatus as claimed in claim 4, wherein said ear rod positioning means comprises: a disc rotatably mounted on said support arm between said pair of spaced support members; and, a pair of connecting links, one of said connecting links running from one off-center position on one surface of said disc to one of said pair of spaced support members and the other of said links running from a second off-center position on the same surface of said disc to the other of said pair of spaced support members, said off-center positions being diametrically located on opposite sides of the center of said disc.
Claim 7
Dependent Claim
106 words
A head-position adjusting apparatus as claimed in claim 1, wherein said ear rod positioning means comprises: a disc rotatably mounted on said support arm between said pair of spaced support members; and, a pair of connecting links, one of said connecting links running from one off-center position on one surface of said disc to one of said pair of spaced support members and the other of said links running from a second off-center position on the same surface of said disc to the other of said pair of spaced support members, said off-center positions being diametrically located on opposite sides of the center of said disc.
